2021-01-12clk: ti: add gate clock driverDario Binacchi
The patch adds support for TI gate clock binding. The code is based on the drivers/clk/ti/gate.c driver of the Linux kernel version 5.9-rc7. For DT binding details see: - Documentation/devicetree/bindings/clock/ti/gate.txt Signed-off-by: Dario Binacchi <dariobin@libero.it>
2021-01-12clk: ti: add divider clock driverDario Binacchi
The patch adds support for TI divider clock binding. The driver uses routines provided by the common clock framework (ccf). The code is based on the drivers/clk/ti/divider.c driver of the Linux kernel version 5.9-rc7. For DT binding details see: - Documentation/devicetree/bindings/clock/ti/divider.txt Signed-off-by: Dario Binacchi <dariobin@libero.it>
2021-01-12clk: ti: am33xx: add DPLL clock driversDario Binacchi
The digital phase-locked loop (DPLL) provides all interface clocks and functional clocks to the processor of the AM33xx device. The AM33xx device integrates five different DPLLs: * Core DPLL * Per DPLL * LCD DPLL * DDR DPLL * MPU DPLL The patch adds support for the compatible strings: * "ti,am3-dpll-core-clock" * "ti,am3-dpll-no-gate-clock" * "ti,am3-dpll-no-gate-j-type-clock" * "ti,am3-dpll-x2-clock" The code is loosely based on the drivers/clk/ti/dpll.c drivers of the Linux kernel version 5.9-rc7. For DT binding details see: - Documentation/devicetree/bindings/clock/ti/dpll.txt Signed-off-by: Dario Binacchi <dariobin@libero.it>
2021-01-12clk: ti: add mux clock driverDario Binacchi
The driver manages a register-mapped multiplexer with multiple input clock signals or parents, one of which can be selected as output. It uses routines provided by the common clock framework (ccf). The code is based on the drivers/clk/ti/mux.c driver of the Linux kernel version 5.9-rc7. For DT binding details see: - Documentation/devicetree/bindings/clock/ti/mux.txt Signed-off-by: Dario Binacchi <dariobin@libero.it>
2021-01-12clk: add clk_round_rate()Dario Binacchi
It returns the rate which will be set if you ask clk_set_rate() to set that rate. It provides a way to query exactly what rate you'll get if you call clk_set_rate() with that same argument. So essentially, clk_round_rate() and clk_set_rate() are equivalent except the former does not modify the clock hardware in any way.

2021-01-12bus: ti: add minimal sysc interconnect target driverDario Binacchi
We can handle the sysc interconnect target module in a generic way for many TI SoCs. Initially let's just enable domain clocks before the children are probed. The code is loosely based on the drivers/bus/ti-sysc.c of the Linux kernel version 5.9-rc7.

2021-01-12spi: omap3_spi: Fix speed and mode selectionVignesh Raghavendra
McSPI IP provides per CS specific speed and mode selection. Therefore it is possible to apply these settings only after CS is known. But set_speed and set_mode can be called without bus being claimed, this would lead driver to set up wrong CS (or previously used CS). Fix this by apply set_speed and set_mode only if bus is already claimed. Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Tested-by: Miquel Raynal <miquel.raynal@bootlin.com>
2021-01-12spi: ti_qspi: Fix "spi-max-frequency" error path in ti_qspi_ofdata_to_platdataOvidiu Panait
struct ti_qspi_priv->max_hz is declared as unsigned int, so the following error path check will always be false, even when "spi-max-frequency" property is invalid/missing: priv->max_hz = fdtdec_get_int(blob, node, "spi-max-frequency", -1); if (priv->max_hz < 0) { ... } Replace the fdtdec call with dev_read_u32_default() and use 0 as the default value. Error out if max_hz is zero. Signed-off-by: Ovidiu Panait <ovidiu.panait@windriver.com>
2021-01-12gpio: tca642x: fix input subcommand for gpio banks > 0Tomas Novotny
The value of input pin for bank > 0 is always 0 for input subcommand. The reason is that gpio_bank variable is computed only for invert and output subcommands (it depends on number of arguments). The default value of zero causes to shift the mask away for banks > 0. Please note that info subcommand works as expected, because the input pin values are accessed differently.

2021-01-05dtoc: Drop dm_populate_phandle_data()Simon Glass
This has not been needed since parent information was added and we started using indicies for references to other drivers instead of pointers. It was kept around in the expectation that it might be needed later. However with the latest updates, it doesn't seem likely that we'll need this in the foreseeable future. Drop dm_populate_phandle_data() from dtoc and driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: Rename U_BOOT_DRIVER_ALIAS to DM_DRIVER_ALIASSimon Glass
We use the U_BOOT_ prefix (i.e. U_BOOT_DRIVER) to declare a driver but in every other case we just use DM_. Update the alias macros to use the DM_ prefix. We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro is widely used and there is at least some benefit to indicating it us a U-Boot driver, particularly for code ported from Linux. So for now, let's keep that name. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: Rename DM_GET_DRIVER() to DM_DRIVER_GET()Simon Glass
In the spirit of using the same base name for all of these related macros, rename this to have the operation at the end. This is not widely used so the impact is fairly small. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()Simon Glass
The current macro is a misnomer since it does not declare a device directly. Instead, it declares driver_info record which U-Boot uses at runtime to create a device. The distinction seems somewhat minor most of the time, but is becomes quite confusing when we actually want to declare a device, with of-platdata. We are left trying to distinguish between a device which isn't actually device, and a device that is (perhaps an 'instance'?) It seems better to rename this macro to describe what it actually is. The macros is not widely used, since boards should use devicetree to declare devices. Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is declaring a new driver_info record, not a device. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Add logging when lists_bind_fdt() failsSimon Glass
It is useful to see the error code when this fails. Add logging for this function. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Allow the uclass list to moveSimon Glass
At present the uclass list head is in global_data. This is convenient but with the new of-platdata we need the list head to be declared by the generated code. Change this over to be a pointer. Provide a 'static' version in global_data to retain the current behaviour. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Split out scanning code to dm_scan()Simon Glass
Move the code related to scanning for devices to bind, into a new function. This will make it easier to skip this step with the new of-platdata improvements. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Access device ofnode through functionsSimon Glass
At present ofnode is present in the device even if it is never used. With of-platdata this field is not used, so can be removed. In preparation for this, change the access to go through inline functions. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05dm: core: Use dev_has_ofnode() instead of dev_of_valid()Simon Glass
We have two functions which do the same thing. Standardise on dev_has_ofnode() since there is no such thing as an 'invalid' ofnode in normal operation: it is either null or missing.

2021-01-05spi: Tweak a few strange SPI NOR features for of-platdataSimon Glass
The #define of one struct to another has been around for a while. It confuses dtoc and makes it think that struct spi_flash does not exist. Make a few changes to improve things while we wait for migration to be completed: - Move the 'struct spi_flash' to column 1 so dtoc scans it - Remove the #define when compiling dt-platdata.c - Update the strange mtd_get/set_of_node() functions - Use struct spi_nor in the drivers, so dtoc sees the correct struct Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-05spi: Tidy up get/set of device nodeSimon Glass
This code is a bit odd in that it only reads and updates the livetree version of the device ofnode. This means it won't work with flattree. Update the code to work as it was presumably intended. Signed-off-by: Simon Glass <sjg@chromium.org>
